Colonel Frost Blossom is an unusually small female northern saw-whet owl, or Aegolius acadicus, and a commander of the Northern Kingdoms. She was in charge of the E company in the Frost Beaks division. She speaks in a thick Krakish accent.
She appeared in the Battle of Fire and Ice, landing toward Bubo and asking the situation; they discussed plans and strategies. Bubo was polite, correcting himself when he called her 'ma'am', but the commander corrected him and said, "Just call me Bloss. Most do."
